Starting Pitchers

Kade Anderson is scheduled to start for Seattle after making only a limited appearance at the major-league level. Anderson is 0-0 with a 4.76 ERA and 1.24 WHIP through 5.2 innings, allowing five hits and two walks while recording five strikeouts and surrendering two home runs. Toronto counters with Jose Soriano, who brings considerably more experience into Saturday's matchup. Soriano is 10-7 with a 3.43 ERA and 1.29 WHIP across 144.1 innings. He has allowed 121 hits while recording 143 strikeouts against 65 walks and has surrendered only 13 home runs. Seattle has an obvious uncertainty on the mound because of Anderson's small sample, while Toronto knows much more about what it can expect from Soriano.

Mariners Need More From Their Offense

Seattle comes into Saturday at 64-70 and sits three games behind first place in a tightly packed American League West. The Mariners have been inconsistent recently, going 3-2 over their last five completed games before Friday's series opener. They defeated Philadelphia 9-2 and 4-1 before being shut out 6-0 in the series finale. Seattle also split its previous two games against Chicago, winning 5-4 before suffering a 19-2 defeat.

Offensive production has been one of Seattle's biggest problems this season. The Mariners are batting just .228 with 526 runs, 1,012 hits and 155 home runs. Their .309 on-base percentage is slightly better than Toronto's, but Seattle owns only a .375 slugging percentage. The Mariners have generated more home-run power than Toronto, yet that hasn't translated into a meaningful advantage in total scoring, with the clubs separated by only three runs for the season.

Seattle's pitching numbers are relatively respectable. The Mariners have posted a 4.10 ERA and 1.24 WHIP, with opponents batting .248 against them. Their WHIP is particularly encouraging compared with Toronto's 1.32 mark. The concern Saturday is whether those season-long numbers will carry over with a starter who has logged fewer than six innings at this level.

Blue Jays Have the Starting Pitching Advantage

Toronto enters the matchup at 65-70 and has struggled to build any sustained momentum. The Blue Jays went just 2-3 over their last five completed games before Friday's series opener. Their most recent completed game was an ugly 13-2 loss at home, although they had shut out the same opponent 3-0 one day earlier. Toronto has scored three runs or fewer in four of those five games, putting considerable pressure on its pitching staff.

The Blue Jays have a .245 team batting average, giving them a clear 17-point advantage over Seattle. Toronto has accumulated 1,116 hits compared with Seattle's 1,012, but the Blue Jays have produced only 126 home runs. Their .306 on-base percentage and .379 slugging percentage are also modest, and their 529 runs scored are almost identical to Seattle's 526. Toronto gets more hits, while Seattle has compensated with substantially more power.

Toronto carries a 4.00 team ERA with a 1.32 WHIP and .240 opponent batting average. The ERA and opponent batting average are both better than Seattle's marks, although the Mariners have the superior WHIP. Saturday's most important advantage for Toronto could simply be the starting pitching matchup. The Blue Jays have a proven starter who has worked 144.1 innings, while Seattle's starter has only 5.2 innings of experience reflected in the supplied statistics.

Seattle Mariners vs Toronto Blue Jays Picks and Prediction

Pick: Toronto Blue Jays ML (-126)

Toronto doesn't have enough of an overall statistical advantage to justify laying -1.5 runs, but Blue Jays -126 on the moneyline is much more attractive. These teams have almost identical records and have scored nearly the same number of runs, but the starting pitching matchup tilts the handicap toward Toronto. The Blue Jays' starter owns a 3.43 ERA over 144.1 innings and has allowed only 13 home runs, while Seattle is asking a starter with just 5.2 innings on his statistical line to handle a road start. Toronto also owns the better team batting average, ERA and opponent batting average while playing at home. At a manageable -126 price, the Blue Jays are the preferred side.

Pick: Under 7.5 (-114)

The Under 7.5 at -114 is a tight number, but the season-long offensive production points toward a lower-scoring game. Seattle has scored only 526 runs through 134 games, while Toronto has managed 529 through 135. The Blue Jays have scored three runs or fewer in four of their last five completed games, and Seattle was shut out in its most recent completed game. Toronto's starter has a 3.43 ERA, and neither offense has consistently produced enough runs to make an Over attractive at this number. Seattle's uncertainty on the mound creates some risk, but the broader offensive numbers make the Under the better play.

Final Picks: Toronto Blue Jays ML (-126) and Under 7.5 (-114).
