AUGUST 7: Righty Dawrin Frias will head to Oakland to complete the deal, the A’s announced. The 23-year-old has been hit hard at the Class A level this year, while also showing significant control problems.

AUGUST 4: The Mets announced tonight that they have acquired left-handed reliever Eric O’Flaherty and cash considerations from the Athletics in exchange for a player to be named later. Fellow southpaw reliever Alex Torres has been designated for assignment to clear space for O’Flaherty on the 40-man and 25-man rosters.

The Athletics designated O’Flaherty for assignment over the weekend to clear a roster spot for trade acquisition Aaron Brooks. The former Braves setup ace was in the second season of a two-year, $7MM contract he signed prior to the 2014 campaign as he recovered from 2013 Tommy John surgery.

O’Flaherty, 30, was sharp in 2014 — his first year back from Tommy John surgery — working to a 2.25 ERA with 6.8 K/9 against 1.8 BB/9 in a small sample of 20 innings at the big league level. His backloaded contract paid him just $1.5MM in 2014 due to uncertainty surrounding how much he’d be able to pitch and $5.5MM in 2015, with the A’s expecting him to be a significant piece in their bullpen.

That didn’t work out, though, as O’Flaherty has struggled to a 5.91 ERA in 2015. While a .354 BABIP has been a significant factor in the regression of O’Flaherty’s ERA, so, too, a marked step back in his control. O’Flaherty averaged just 2.3 unintentional walks per nine innings from 2009-14 after establishing himself as a quality relief option in the Majors, but he’s issued 12 unintentional free passes in 21 1/3 innings this season. On the plus side, O’Flaherty has a track record of success — he posted a 1.99 ERA, 7.2 K/9 and 2.9 BB/9 in 249 1/3 innings from 2009-13 with Atlanta — and he’s dominated opposing lefties in 2015, holding them to a .186/.286/.209 batting line.

O’Flaherty is owed about $1.86MM through season’s end, though the A’s appear to be picking up at least some of the tab there. He becomes the second reliever to make the cross-country journey from Oakland to Queens, as he’ll join former teammate Tyler Clippard in manager Terry Collins’ bullpen.

Torres doesn’t immediately look like a DFA candidate upon first glance, as he’s worked to a 3.15 ERA and struck out 35 batters in 34 1/3 innings. However, Torres has also walked 26 batters this year, and opposing lefties are hitting an alarming .268/.406/.393 against him in 69 plate appearances. Torres’ ERA is largely a product of a minuscule .233 BABIP and a bloated 83 percent strand rate — neither of which figures to be sustainable down the stretch.

A relatively quick DFA certainly isn’t what the Mets had in mind this spring when they traded Cory Mazzoni and a player to be named later (Brad Wieck) to the Padres in exchange for what they hoped to be several years of Torres’ services. Torres is not yet arbitration eligible — though he will be this winter — and enjoyed better performances from 2013-14 with the Rays and Padres, so perhaps a team looking for left-handed bullpen depth will give him a look if he’s placed on outright waivers. If not, the Mets will be able to outright him to Triple-A Las Vegas and keep him in the organization with the hope that some time in the minors will help to sort out his command issues.
