The mayhem of the non-waiver trade deadline has come and gone, but that doesn’t mean teams have stopped tweaking their rosters in an ever-increasing effort to join the ranks of postseason contenders. The Mariners emerged from last week’s deadline with Orioles’ starter Ariel Miranda, effectively trading back-end starter Wade Miley for Miley’s cheaper, younger doppelganger. It wasn’t a bold move, and certainly not one that can boost the club from the middle of the AL West standings, but general manager Jerry Dipoto doesn’t appear to be finished just yet. On Saturday, the Mariners dealt a player to be named later (as well as a conditional PTBNL) in exchange for Pirates’ right-handed reliever Arquimedes Caminero.

Although the Pirates cleared some much-needed room in their bullpen, they also shed one of the fastest arms in the major leagues. At 29 years old, Caminero wields a fastball that averaged 98 mph on the radar guns in 2016, down just a tick from a peak velocity of 99 mph through the 2015 season. His heater fuels a 3.51 ERA and 4.74 FIP, accentuated by a hefty strikeout rate of 7.0 whiffs per nine innings pitched. While his speed may have been a selling point for the Mariners, it comes with an unappealing side of control issues. Through 41 innings in 2016, the right-hander’s 4.8 BB/9 rate is the second-highest of his career to date.

On the heels of Caminero’s trade to Seattle, the Mariners dealt another PTBNL for famed switch-pitcher Pat Venditte. Venditte hails from Toronto, where he pitched 8 2/3 innings for the Blue Jays as they stormed their way to the top of the AL East standings. His ambidextrous approach has been well-documented, but the bulk of his work has come through the Blue Jays’ Triple-A affiliate, where he recorded a 4.37 ERA through 35 innings in 2016. Neither Miranda, Caminero, or Venditte are likely to give the Mariners the big push they need to lock down a wild card spot, let alone the division, but diversifying their pitching staff should help them stay competitive as the season winds down.
