OFFICIAL: @Dbacks recall RHP Chase Anderson (@Chaser34) from Double-A Mobile and option RHP Mike Bolsinger to Reno
— Arizona Diamondbacks (@Dbacks) May 6, 2014
Actually, think Anderson's Twitter handle is @ChaseAnderson87, not the guy with no Tweets and three followers. That said, curious to see whether this is a long-term or short-term move: with Bolsinger having started last night, it's possible this could be adding an extra bullpen arm until the next time that spot in the rotation rolls around [and with an off-day for the Diamondbacks coming up on May 8th, along with others on the 15th and 19th, it will be a while before we'll regularly need a #5]. Anderson is definitely a starter this year, but half his appearances with Reno last season were out of the 'pen, so it might work both ways: reliever immediately, starter as needed.
Anderson has been absolutely destroying opposing hitters in Double-A this year. In six starts, he has thrown 39 innings and allowed three earned runs, for an ERA of 0.69. A K:BB ratio of 38:6 also suggest he was not exactly being challenged by the level, but Anderson was old for that level, having turned 26 last November. John B had been pushing for a promotion, but that it comes to the majors, and by skipping Triple-A entirely, is something of a surprise. As mentioned, Anderson did play for Reno last year, and the results there were pretty meh, a 5.73 ERA over 88 innings, with an 80:33 K:BB ratio. We'll see if he can do better now.
To be blunt, Bolsinger largely demonstrated why people hadn't heard of him prior to his call-up. He had one good start in four attempts, not getting past the fifth or allowing fewer than four earned runs in the other three. He may have punched his own ticket out, early last night. Before yesterday's game, Kirk Gibson "mentioned the aggressiveness of Milwaukee Brewers leadoff man Carlos Gomez, noting how often he tends to swing at the first pitch and how careful his pitchers would need to be in attacking him." Bolsinger wasn't apparently listening, and one pitch later, Gomez was trotting round the bases. That kind of thing tends not to sit well with Gibby.
That wasn't the only move officially announced. As discussed by Gibson last night [in lieu of talking about Bolsinger's status!], J.J. Putz was put on the DL with a forearm issue, and Evan Marshall promoted. Marshall had come on to the radar with a 15.2 inning scoreless streak to start the season with the Aces. He finally allowed a run on Saturday, but in 16.2 innings, the right-hander has held the opposition to a .175 average, with a K:BB ratio of 19:5. We'll see how serious the Putz injury turns out to be. Going by precedent, they'll probably carry out Tommy John surgery, just as a precaution...
