HOUSTON — Every few minutes, a new player arrived at the Toronto Blue Jays road clubhouse. Spencer Arrighetti walked across the hall from the home side while Josh Smith and Jameson Taillon strolled in before batting practice. José Soríano was the last of Toronto’s MLB trade deadline additions to show up, driving down the tunnel in a golf cart just before Monday’s first pitch. Eventually they’d all arrived.The Jays acquired 10 players on deadline day, including four big leaguers. Here’s what you need to know about each of them:SP José SoríanoOver the last three seasons, Soríano sits 23rd in ERA among pitchers with at least 400 total innings (3.73). That’s just behind Dylan Cease (3.59) and just ahead of the recently departed Kevin Gausman (3.88). Acquired for Arjun Nimmala and two other prospects, Soríano immediately becomes the Jays’ No. 2 starter and should fill that role for the multiple seasons. He’s under team control through 2028.Soríano’s primary pitch is a sinker, which leads to one of baseball’s highest ground ball rates (52.3 percent, per Baseball Savant), alongside a curveball, fastball, splitter and slider. The Jays, manager John Schneider said, don’t expect massive arsenal tweaks for Soríano. They like the stuff, but just want it more in the zone.“Trying to limit the walks,” Schneider said, “and trying to not be on the edges as much.”The Jays have had recent success harnessing effectively wild arms, such as Cease, Robbie Ray and Yusei Kikuchi. Even if they don’t get Soríano to throw more strikes, he’s still a top-half rotation arm to build around.The 27-year-old, who hasn’t pitched since July 26, will make his Jays debut on Friday against the Philadelphia Phillies.Which MLB teams did the most?Levi Weaver and Madison EadesSP Spencer ArrighettiArrighetti, sitting in the Daikin Field news conference room in his new Jays gear, wasn’t quite ready to say goodbye to the Astros. The right-hander is from Houston and grew up an Astros fan. Playing on the same team as George Springer, he said, will be “really special.” As with Louis Varland in Minnesota, the Jays hope to pluck a local boy in Arrighetti and get the most out of him.Arrighetti is similar to Soríano, with less MLB success. He suppresses hard contact and strikes batters out, but misses his spots and walks batters far too often. In 53 MLB appearances, Arrighetti has a 4.66 ERA with 4.5 walks per nine innings.“The zone’s really small now,” Arrighetti said. “I’ve just kind of been working on not walking people, and I feel like I’m actually taking some really good strides, leaning into the pitches that I throw in the zone.”In his first bullpen session with the Blue Jays’ pitching coaches, Arrighetti said, they’re already “refining” with a few small tweaks. The righty declined to reveal those adjustments, but said the data on his pitches was “exciting.”One thing to note about the 26-year-old starter is that he has three option years remaining, which means he can be sent down to Triple A this season and in the next two. For a team that will need capable rotation depth moving forward, that optionality is particularly valuable.Recently recovered from right foot nerve irritation, Arrighetti will begin a rehab assignment with Triple-A Buffalo on Thursday.SP Jameson TaillonTaillon knew there was a possibility he’d be traded to Toronto this week. The Jays called him when he was a free agent in 2022 and he knew they had called the Cubs when he was designated for assignment on July 27. The 34-year-old, with Canadian parents who met at the University of Toronto, is now finally a Jay.
