Francisco Rodriguez retired all four batters he faced to record his 28th save of the season in Monday's win over the Red Sox.
The Tigers turned to K-Rod with the bases loaded and two outs in the eighth, and he got Mookie Betts to ground into a fielder's choice. The closer then retired the Red Sox 1-2-3 in the ninth. K-Rod has mostly been excellent since a couple rough outings in April.
Daniel Mengden was lifted after allowing four runs in 4 2/3 innings Monday in a no-decision against the Rangers.
Mengden doesn't have a single quality start in five tries this month; he's given up 23 earned runs over 23 innings. It's time for him to head back to Triple-A, though whether that happens could hinge on Rich Hill's status. One thing is for sure: Jesse Hahn is more deserving of the rotation spot right now (though there might be room for both).
Ryan Madson took his sixth blown save after giving up a two-run homer to the Rangers in Monday's loss.
Madson has given up a whopping five homers and 10 runs in his last 12 innings of work, so his time as a closer could be coming to a close. Ryan Dull has looked like Oakland's best reliever all season long and is worthy of an opportunity.
Orioles optioned OF Dariel Alvarez to Triple-A Norfolk.
The move is expected to clear the way for Hyun Soo Kim to return from the disabled list. Alvarez is 1-for-3 with a double in two games with the Orioles this season and should be back later this summer.
Danny Valencia went 2-for-4 with a homer and three RBI against the Rangers in a loss Monday.
Valencia is the hitter the A's wanted Billy Butler to be when they gave him a three-year deal prior to 2015, and the A's have responded to it by cutting back his playing time against righties lately. It doesn't make a lot of sense to us. Valencia isn't great against righties, but neither are the alternatives the A's possess. Ideally, Valencia would get traded this week.
