Earlier today, the Giants acquired left-handed reliever Jose Mijares from the Kansas City Royals via waivers. The Giants simply claimed him off waivers and didn’t have to give up anything in return, so they basically got him for free. Mijares, 27, doesn’t hit free agency until 2015, and he’s actually having a very good season: he’s tossed 38.2 innings across 51 appearances, posting a 163 ERA+ with fairly strong peripherals (8.6 K/9, 3.0 BB/9, and 0.7 HR/9). His FIP currently sits at a solid 3.50. And he is, of course, especially tough on left-handed hitters. For his career, he’s held lefties to a .606 OPS, which is right in line with what he’s done this season (.601 OPS).

He’s a flyball-heavy pitcher, having induced one groundball for every two flyballs over his career. But he’s consistently managed to keep his home run rate in check, which — at least in part — appears to be a sustainable skill. 20% of his career flyballs have been infield flies, which is very good relative to the league average rate over that span (13%).

For reasons beyond my knowledge, more than 20 teams passed on the opportunity to grab Mijares. It’s peculiar, and I’m not the only one that thinks so. In any event, it worked out perfectly for the Giants, and you have to hand it to them for this acquisition. They just bolstered their bullpen at zero cost, and they’ll now have a cheap lefty specialist for the foreseeable future. Mijares is essentially insurance against future overspending on LOOGYs.

Now comes a pretty important question: who goes? The Giants will have to make room for Mijares in the bullpen, and there’s some sentiment that George Kontos (given his minor-league options) could be sent back down to Fresno. Kontos (2.42 ERA/2.99 FIP/3.28 xFIP) has been outstanding thus far, so needless to say, that would be foolish. Alex Pavlovic writes that Brad Penny and Shane Loux, not Kontos, are the most likely candidates to go — and hopefully that’s the case.
