The set-up: The Mariners won 4-2 in the opener of their three-game home series with the Blue Jays but Toronto bounced back with a similar 4-2 win last night. The teams play the rubber game of the series on Sunday, as the Mariners cap an 11-game homestand (are 7-3 so far). Seattle opened the season 2-8 but has rebounded lately, winning 10 of 13 to sit just one game under .500 (31-32). The bad news is, Seattle resides in the AL West with the 44-19 Astros, so the Mariners are 13 games out of first place. Toronto knows all about slow starts, as the Blue Jays opened 2-11 in 2017. They had gotten to within one game of .500 on June 4 (28-29) but have now lost three of five since. However, despite finding themselves in last place at 30-32, Toronto is 'only' 7 1/2 games out of first in the AL East.

The pitching matchup: J.A. Happ (0-4 & 5.33 ERA) toes the rubber for Toronto and James Paxton (5-0 & 1.69 ERA) gets the nod for Seattle. Coming off a 20-4 season in 2016, Happ has been limited to just five starts in 2017 because of injury and is still looking for his first win of the season. He allowed five runs on four hits and three walks in 5 1/3 innings of a 5-3 loss at Oakland on Monday but it was the second-longest outing of the year. Happ spent part of 2015 with Seattle and is 3-1 with a 4.50 ERA in five career starts against his former team (teams are 3-2). While Happ seeks his first win of 2017, Paxton has yet to suffer a defeat this season in eight starts (he's 5-0 but the team has lost his three no-decisions). Incredibly, Paxton has only allowed runs in three of his eight starts in 2017 and in five home starts this season, is 4-0 (team is 4-1) with a 1.17 ERA and 0.98 WHIP.

The pick: Happ earned his milestone 20th victory of the season at Safeco Field last September, so maybe this start will be his "lucky day" (first win of 2017)? Paxton has been "lights out" at home in 2017 and neither team has shown much offense this weekend, scoring six runs apiece after two games. Make the Under an 8* play.
