Mariners rookie starter Taijuan Walker will make his final start of the 2013 season against the Astros on Monday, reports MLB.com’s Greg Johns. Brandon Maurer will take his spot in the rotation.
Walker spent most of his season between Double-A Jackson and Triple-A Tacoma, posting an aggregate 2.93 ERA in 141.1 innings. He made his Major League debut on August 30 against the Astros, shutting them out on two hits and a walk in five innings. His second start didn’t go as well, as he allowed four runs to the Royals in five frames.
MLB.com ranked Walker, drafted by the Mariners 43rd overall in the 2010 draft, as the #5 overall prospect entering the season. He is expected to be a mainstay in the Seattle rotation starting next season.
Jon Morosi of MLB Network and FOX Sports reports that the Mariners have acquired starter Chris Heston from the Giants. The Giants will receive a player to be named later, per Jon Heyman of FanRag Sports.
Heston, 28, logged only five innings in the majors this past season as he battled an oblique injury and otherwise spent most of his time with Triple-A Sacramento. Heston was solid out of the Giants’ rotation in 2015, posting a 3.95 ERA with a 141/64 K/BB ratio in 177 2/3 innings over 31 starts.
Heston will be under team control through 2021. He’ll provide depth for the Mariners’ rotation in the meantime.
Joe Nathan‘s agent, David Pepe, says his client wants to pitch in 2017, per ESPN’s Jerry Crasnick. “He’s like the Energizer Bunny,” Pepe said.
Nathan, 42, came back from Tommy John surgery in July, pitching two scoreless innings for the Cubs with four strikeouts and two walks. The Cubs released him and the Giants picked him up, and Nathan went on to pitch 4 1/3 scoreless innings down the stretch with five strikeouts and two walks.
According to FanGraphs, Nathan’s velocity wasn’t where it used to be, which is to be expected of a pitcher in his 40’s coming back from major elbow surgery. Still, with teams always on the hunt for bullpen depth, it would be shocking if Nathan didn’t get any bites before spring training starts.
