Whataburger Field, home of the Corpus Christi Hooks, AA affiliate of the Houston Astros, was awarded the Sports Turf Managers Association’s 2009 Professional Baseball Field of the Year Award. The crew was led by field superintendent Garrett Reddehase, who was promoted after the season to take over duties at AAA affiliate Round Rock. He credits full-time assistant Josh Brewer and season crew members Eric Ortiz, Robbie LaCount, Brady Tumlinson and Ryan Servantes for their valuable contributions to winning the award.


Whataburger Field is located on land once covered by cotton warehouses at the Port of Corpus Christi, TX. Large, oceangoing vessels navigate the channel that runs just beyond the stadium. Prevailing southeasterly winds create significant issues with turf salinity and irrigation. In 2009, the area went through its worst drought since 1917 and saw average temperatures 4 degrees above normal. Reddehase says they received only 3 ¼ inches of rain from January to August, and half of that came in 1 day.


These conditions created challenges; the crew was forced to hand water many areas of the outfield because the irrigation system was not able to provide complete coverage due to gusting winds and high temperatures. But Reddehase & Co. successfully kept the playing surface in stellar condition, aerifying and managing the sodium levels, even after 13 games in a 4-day tournament, part of a 34 games in 33 days stretch.


Whataburger Field was completed in 2005 and last year saw nearly 600 hours of action, plus another 225 hours of concerts, banquets, charity events and corporate parties. The field is TifSport bermudagrass and includes patches of GN1 and common Bermuda scattered throughout. It is overseeded in mid-December with 400-600 pounds of perennial ryegrass. It features a 12-inch sandy rootzone on top of 4 inches of pea gravel.


Each year the infield skin is laser-graded and new material added (nearly 11 tons of Diamond Pro calcined/vitrified clay in 2009). Last year the bullpens were renovated; approximately 1,500 square feet of turf 5 inches deep (root removal included) was removed from each bullpen. Four tons of sand and crushed brick was added and leveled so turf could be applied. Six 250-square foot pieces of turf were added to each pen; the turf came from the New Orleans Superdome. Each piece weighed nearly a ton because the used turf included the rubber infill. Result of this renovation is savings in water, fertilizer and man hours.


“The Corpus Christi Hooks are thrilled to have Whataburger Field recognized as the 2009 professional [baseball] field of the year,” says Hooks general manager Michael Wood. “From the beginning of his time here, Garrett has shown a drive for excellence and a passion to grow his knowledge base and skill set. That, along with the ability to assemble and manage a top-notch field crew, has enabled him earn the respect of his peers. We’ve always known he did a great job; we’re excited to see others acknowledge it.”


SportsTurf: What if any changes do you expect in your maintenance practices at the AAA level?


Reddehase: I plan to keep my maintenance practices pretty much the same while in Round Rock. In Corpus Christi, we had to monitor the sodium level on a regular basis with the ballpark being located next to the bay, and constantly battled the soaring winds that came off the Gulf.  Other than that, it’s pretty much the same routine. If you can stick to that routine, it’s going to work out for the most part.


ST: What’s the most important piece of equipment or product in your program?


Reddehase: The most important piece of equipment in my program is not equipment at all. My crew is the most important asset to the success of maintaining a safe environment for players as well as being aesthetically pleasing to the fans, and a place the community can be proud of. I was very fortunate to have a great group of guys that I could trust and depend on, and the front office personnel as well. We rely on the staff as a whole to help with tarp pulls and other situations that came up, and their response is greatly appreciated. 


ST: How do you communicate with the front office, managers, coaches and players?


Reddehase: The front office of the Corpus Christi Hooks and Ryan-Sanders Baseball are amazing. It’s truly a group effort, from upper management pulling tarp in their slacks, to ticket guys helping us out with the infield drag when we are short on staff. Tina Athens, our stadium operations director, helped us in many ways; she always has the best interest of the field, and our crew in mind. Our President, Ken Schrom, is a very approachable guy. With his experience in the big leagues he understands the effort that goes into maintaining the field. Our GM, Michael Wood, has provided constant support and trust which motivated me and my crew tremendously. I tried to have an open-door policy with the players and coaches. At the beginning of the year, we would introduce ourselves as a staff and I would let them know if something wasn’t playing right, or if they wanted areas a different way to let me know so we could accommodate them the best would could. Before long, we had to check and see who was pitching that night because every pitcher wanted the mound a different way!


ST: What’s the best piece of turf management advice you’ve ever received?


Reddehase: The best piece of turf management advice I have ever received was from former Hooks and Express field superintendent Brad Detmore. He would always tell me “the players and coaches notice how well the field plays, and the fans notice how green the grass is. How the field plays is the most important, and if you can please them all, you’re on the right track.” 


ST: How do you balance work and personal life?


Reddehase: Balancing work and my personal life are very challenging. Fortunately I have a very understanding wife that knows my career requires a lot of my time especially during the season, so I try to make up for that lost time when the season is over! 


ST: What have been the most important reasons you have progressed so well in your career?


Reddehase: I think some of the reasons I have been fortunate to progress in my career are that I have a great work ethic, and have been blessed with a great crew. The Ryan-Sanders organization was willing to take a chance on me and provide us with the means to maintain a great field. I have had the privilege of working for and learning from Brad Detmore, and I have been able to build a great network of people of whom I can call and ask questions. A manager can never know enough in this career, so asking questions, and researching information is a huge part of our success.

December


400 lbs. of perennial ryegrass blend applied with an Accupro 2000 rotary spreader. Edges applied with rye using a Scott’s drop spreader.

Hand watering continued.


July


Foliar applications were applied every 10-14 days depending on schedule. A surfactant was also applied to help with hydrophobic areas. Mowing continued every day, height moved to 9/16 inch because of drought-like conditions. Hand watering continued on infield and sidelines, as well as branching out to parts of the outfield.
