Rob Refsnyder jolts Mariners lineup: New leadoff look vs first lefty starter
rob refsnyder is at the center of a striking new look for Seattle as the Mariners unveil their first lineup of the season against a left-handed starter on Saturday. At 2: 02 PM ET on March 28, 2026, the Mariners posted a batting order that places their newest veteran at the very top, with first pitch set for 6: 40 PM ET against the Cleveland Guardians in Game 3 of 162. The shift matters because Seattle built this offseason addition to steady a lineup that can skew heavily left-handed when fully healthy.
Rob Refsnyder debuts at the top against Joey Cantillo
In the Mariners’ first lineup versus a lefty starter this season, rob refsnyder is batting first as the designated hitter in his team debut against Guardians left-hander Joey Cantillo. The move immediately reshapes the rest of the order: third baseman Brendan Donovan slides from the leadoff spot down to sixth, while switch-hitting shortstop Leo Rivas moves from ninth to eighth, swapping places with second baseman Cole Young.
Seattle is also getting another new name into the mix. Victor Robles is making his season debut as well, batting seventh while starting in right field.
Why Seattle wanted this specific lineup balance
The Mariners brought Refsnyder in during the offseason with a clear roster goal: help balance a lineup that gets “very left-handed heavy” at full strength. Through the first two games, Seattle used five left-handed bats in its lineup against right-handed starters, and the club expects that number to rise to six left-handed-hitting regulars once shortstop J. P. Crawford returns from the injured list. The team believes Crawford could be back as soon as its first road trip.
Refsnyder’s role is tightly connected to that matchup problem. Over the past four seasons, he has been among baseball’s best hitters against left-handed pitching. Since the start of 2022, he has a. 312/. 407/. 516 slash line and a. 924 OPS in 501 plate appearances versus southpaws. He entered the season ranked third among MLB hitters in on-base percentage against lefties over that span (minimum 400 plate appearances), behind Aaron Judge and Paul Goldschmidt, while also ranking sixth in batting average, 16th in slugging percentage, and seventh in OPS.
Game timing, pitching, and where the roster stands right now
Saturday’s matchup is scheduled for 6: 40 PM ET, with pregame radio coverage beginning at 5: 30 PM ET. On the mound for Seattle, right-hander Bryan Woo is set to make his first start after an All-Star 2025 campaign.
The lineup change also lands on a day when Crawford’s status is moving. The Mariners shortstop was back with the team Saturday and could begin a rehab assignment early next week, Mariners insider Shannon Drayer said.
Immediate reactions inside the organization
The Mariners’ public messaging on Saturday underscored the moment: the club posted that Bryan Woo pitches today, as the new batting order drew attention for its reshuffled top. Internally, the intent is straightforward and stated: Seattle added Refsnyder to counterbalance left-handed heaviness and to give the lineup a different shape against left-handed starters.
What’s next
All eyes now turn to Saturday night’s first test of this alignment against a lefty starter, with rob refsnyder immediately asked to set the tone from the leadoff spot in his Mariners debut. After this game, the next pivot point will be the club’s handling of J. P. Crawford’s rehab timeline early next week, a development that could further change how Seattle structures its lineup on the road.
