In the Diamondbacks' entry for "Least Surprising Roster Move of 2012," the team has announced that Trevor Bauer has been promoted from Reno, with Josh Bell being optioned to our Triple-A affiliate. Bauer will, of course, be making his major-league debut this afternoon for the Diamondbacks in Atlanta. Since his call up in mid-May, Bell hit .173/.232/.269 in 56 PAs for Arizona, so didn't do much to stake a claim to stay here.
The move does leave Arizona a tad thin at third-base behind Ryan Roberts. While RyRo has been hitting somewhat better of late - he has gone .274/.286/.468 since June 3 - this switch means none the other players who have started games there for us this year (Bell, Cody Ransom and Geoff Blum) are now on the roster. Blum is down on a rehab assignment with the Aces, but in nine games has gone 4-for-27 (a .148 clip), though with a nice K:BB ratio of 3:8. There's also the question, looming since the signings of John McDonald and Willie Bloomquist, of who he'd bump off the roster, now Stephen Drew is back.
And in case you're wondering, McDonald and Bloomquist don't have much experience at third, with only 63 and 85 career starts there respectively. While they could no doubt start in a pinch, it looks like Roberts will be the Diamondbacks starting third-baseman going forward.
