Ryan Mountcastle

Now official is the second biggest contract in Orioles' history. Hopefully, it works out a whole lot better than the biggest, which was Chris Davis's seven-year, $161 million deal signed 10 years ago. Alonso will likely hit third or fourth for the Orioles, and he should benefit some from the move out of Citi Field, though more so from a singles and doubles standpoint than when it comes to homers. The signing frees up to the Orioles to part with Ryan Mountcastle and/or Coby Mayo. One of the two could be part a DH rotation, but neither seems entirely necessary at this point. If both do stick around, Mayo will probably return to Triple-A.

The Orioles finally did it. Matching the Phillies' five-year, $150 million offer to Kyle Schwarber didn't work out, but the Mets probably weren't similarly motivated to pay Alonso quite this much, at least not for so long. The 31-year-old Alonso is coming off perhaps his most impressive season since his rookie campaign, having hit .272/.347/.524 with 38 homers and 126 RBI. His average exit velocity off the bat was 93.5 mph, which is about four mph ahead of where he was from 2022-24, and his .385 xwOBA was a career high. His 89 barrels were 23 more than he'd ever collected before. With Alonso slotting in at first base, one imagines the Orioles will seek to move Ryan Mountcastle and Coby Mayo, though it's possible they could keep one as a DH option.
