Collmenter assures Gibson he's healthy
By Steve Gilbert / MLB.com
WASHINGTON -- D-backs manager Kirk Gibson met with Josh Collmenter on Monday, and the right-hander will remain in the rotation while the team keeps an eye on his workload.
Collmenter struggled Sunday afternoon in Miami, with his velocity down early in the game, leading to questions about whether he is being asked to make too big of an innings jump from last season to this season.
Collmenter threw 92 innings out of the bullpen in 2013 and is already at 129 1/3 this season after being thrust into the rotation in April.
"I talked to Colly today and he just felt sluggish," Gibson said. "It was one of those days. It happens from time to time. If it's something that continues to go on, then you have to dig deeper into it."
The main thing Gibson wanted to ascertain was whether Collmenter was feeling any physical discomfort.
"He assures me he feels fine," Gibson said. "His shoulder isn't sore, his elbow is not sore. It's something he has to be honest with us about. At this point, he says he's fine."
Collmenter is scheduled to start Friday against the Padres at Chase Field.
Trumbo not being moved off first base
WASHINGTON -- Mark Trumbo got the starting nod in left field Monday night, but manager Kirk Gibson said it was not because of Trumbo's struggles at first base over the weekend.
Trumbo had some trouble catching pickoff throws at first base against the Marlins on Saturday and Sunday.
"I wanted to get Jordan Pacheco in the lineup," Gibson said. "I thought the best spot to put him at would be first base, move Mark out there in left field."
Trumbo began the season in left field, but moved to first base after Paul Goldschmidt was lost for the season due to a fractured left hand. Prior to this year, the majority of Trumbo's playing time had come at first base.
Bench coach Alan Trammell talked with Trumbo a little about some adjustments with his positioning and footwork that might help.
"He's a tall guy," Gibson said. "Maybe he's standing up a little more than normal. The other thing is, his glove, his target, is high. Maybe we'll move it down a little bit, spot it down. Any place you're at on defense, you can get a bad hop or get a low throw or high throw. You try to put yourself in the best position you can to be able to react and catch it."
D-backs bring back righty reliever Harris
WASHINGTON -- Will Harris is back again.
The D-backs recalled the right-hander from Triple-A Reno on Monday and optioned Bradin Hagens to Reno.
Hagens was called up last Thursday with the D-backs' bullpen running on fumes following a doubleheader in Cleveland. The right-hander made a pair of appearances and allowed one run in 2 2/3 innings.
This will be Harris' third stint in the big leagues this year. He was on the Opening Day roster and was up for a week in June. After posting a 2.91 ERA for the D-backs in 2013, Harris has a 9.24 ERA in 12 games with Arizona.
With Reno this year, Harris was 3-2 with a 0.99 ERA.
D-backs prospect Blair keeps firing blanks
Right-hander Aaron Blair, the D-backs' No. 4 prospect, struck out seven batters in six scoreless innings Monday as Double-A Mobile defeated Mississippi, 4-2.
Blair, ranked No. 83 on MLBPipeline.com's Top 100 Prospects list, threw 78 pitches, scattering four hits and one walk. He threw six scoreless innings for the second consecutive start and extended his shutout streak to 14 innings.
Blair has had a sensational first full professional season after the D-backs selected him with the 36th overall pick of the 2013 First-Year Player Draft. He began the year with Class A South Bend and earned two promotions to reach Mobile last month.
In 25 starts across all three levels, he is 9-5 with a 3.70 ERA. He has struck out 160 batters and walked 44 in 143 1/3 innings. He ranks second in the Minor Leagues in strikeouts, trailing Class A Advanced Dunedin right-hander Taylor Cole by two.
Third baseman Brandon Drury, the D-backs' No. 6 prospect, went 2-for-4 in the victory, extending his hitting streak to seven games. He is hitting .362/.406/.638 in 16 games since he was promoted from Class A Advanced Visalia at the beginning of August.
