Rockies right-hander Tyler Chatwood and Rangers right-hander A.J. Griffin haven't returned to their dominant first-half forms since they each came off the 15-day disabled list. Now they'll have a chance to get back on track as they face off at Coors Field on Tuesday.
In the 13 starts before straining his mid-back, Chatwood had a 2.89 ERA and averaged 2.8 walks per nine innings. Since the injury his ERA has climbed to 4.94, and he is averaging seven walks per nine. Notably, he walked eight in a five-inning outing on July 24.
"I still walk too many guys, but it's something I've got to keep working on to get better," Chatwood said. "You just keep pitching and get as many reps as you can get."
Griffin was off to the best start of his career, with a 2.94 ERA in six starts, before going down with inflammation in his shoulder. But he's allowed a homer in each of his eight starts since returning from the DL -- 11 total. Since 2012 he has averaged 1.49 home runs per nine innings, fifth highest among pitchers with at least 50 starts.
"Someone has got to do it, so it might as well be me," Griffin said. "They have to deal with the same stuff on the other side. Any time you're pitching in a big league game is a good day."
Three things to know about this game
• Rangers first baseman Mitch Moreland and outfielder Nomar Mazara will be back in the lineup on Tuesday; they didn't start on Monday with a lefty on the mound. Outfielder Carlos Beltran will also return to the lineup after not starting on Sunday or Monday because of a sore left quad.
• Rangers outfielder Shin-Soo Choo is 2-for-10 with a home run off Chatwood. He is the only Rangers player with more than five at-bats off him. First baseman Mark Reynolds and outfielder Ryan Raburn are the only Rockies to face Griffin; they are hitless in three and two at-bats, respectively.
• Rockies right fielder Carlos Gonzalez exited Monday's game after the top of the first with inflammation in his left ankle. He is hitting .336 in day games, with a .621 slugging percentage. Both are the fourth highest in the National League.
