Mariners Acquire Will Klein, Designate Tyler Jay For Assignment

The Mariners have acquired right-hander Will Klein from the Athletics, according to announcements from both clubs. The latter club had designated him for assignment last week. The A’s get international bonus pool space in return, though the exact amount wasn’t specified. The M’s designated left-hander Tyler Jay for assignment as the corresponding move.

Klein, 25, was traded from the Royals to the A’s as part of last summer’s deadline trade that sent Lucas Erceg to Kansas City. Klein has a sliver of major league experience to this point, having tossed 7 1/3 innings between the two clubs last year, allowing nine earned runs.

That means he currently sports an ugly 11.05 earned run average in the bigs, but it’s a tiny sample of work and he averaged 97 miles per hour on his fastball. In general, his pitching on the farm has resulted in heaps of strikeouts and walks. He has thrown 221 1/3 innings across various minor league levels, with a 5.16 ERA, 30.4% strikeout rate and 16.4% walk rate.

Given the poor control, Klein is probably considered something of a project. He still has a couple of options remaining, so the M’s can plug him in as depth while they see if he can rein in his arsenal a bit more.

Jay, 31 in April, was just claimed off waivers from the Brewers earlier this month. He has had a somewhat unique baseball journey, as he was the sixth overall pick in 2015 but various injuries derailed his career. He actually just debuted in the majors last year, almost a decade after being drafted. He tossed 7 2/3 innings between the Mets and Brewers, allowing four earned runs.

It’s hard to glean much from that sample but Jay also tossed 56 2/3 minor league innings last year between those two clubs with a 3.02 ERA. His 20.9% strikeout rate was subpar but he kept walks down to a 5.1% rate and got grounders on 47.3% of balls in play.

The M’s were intrigued enough to grab Jay off waivers but have now bumped him off the roster. He’ll be in DFA limbo for a week at most, waiting to see what comes next, whether that’s a trade or some fate back on the wire. The waiver process takes 48 hours, so any potential trade talks would have to come together in the next five days. He still has options and just a few days of service time, so any acquiring club could perhaps deploy him as a cheap depth arm with roster flexibility.

While it’s not great for the A’s to have already lost one of the three players they got for Erceg, they at least are getting some pool space out of this deal. As mentioned, the exact amount wasn’t reported, but pool space can only be traded in $250K increments. The A’s will get a bump of at least that much, which they can use to add some more talent to their system.
