The Arizona Diamondbacks (12-14) and the Seattle Mariners (13-12) play Friday in the 1st of 3 Games this weekend. First pitch at T-Mobile Park is scheduled for 9:40 p.m. ET (ESPN+). Let’s analyze FanDuel Sportsbook’s lines around the Diamondbacks vs. Mariners odds and make our expert MLB picks and predictions for the best bets.
Season series: 1st meeting; Seahawks won 2-1 last season
Arizona is onto their final series of a 10-game road trip, which began with a 5-0 loss at San Francisco April 18 and watched the D-back flip-flop wins and losses since, going 3-4. LF Lourdes Gurriel Jr. raised his batting average to .300 after going 10-for-24 (.417) over his last 5 games and is tied with 2B Ketel Marte for the team lead in HRs (5).
Seattle is in 1st place by a half game in the AL West after winning 7 of last 9, including 2 of 3 midweek at Texas in Arlington. After a slow start to the season, CF Julio Rodriguez has turned it up a notch at the plate with 6 multi-hit games in his last 8 games. Plus, his 7 SBs are tied for 3rd most in the AL.

Diamondbacks at Mariners picks and predictions
Prediction
Arizona 4, Seattle 3
Moneyline
BET ARIZONA (-130).
Entering Friday, Seattle had the highest team K% in baseball (27.6%) and Gallen has at least 6 K’s in each of his last 4 starts. The Mariners have also hit the least number of doubles, and C Cal Raleigh who leads the team in HRs (6) may have cooled off offensively after having to undergo an emergency dental procedure Wednesday.
Run line
PASS.
Seattle +1.5 (-156) is the hotter team coming into this one, and it’s at home. My lean would be to take the run and a half if I had to make a play.
Over/Under
BET UNDER 7.5 (-115).
MLB Park Factor calculates T-Mobile Park to produce the least amount of runs per game. Plus, Hancock has pitched much better lately, so this could turn into a bit of a pitchers’ duel. Only 5 pitchers out of 121 who have gone at least 20 innings this year have a lower BB% than Hancock (3.3%), so it’s unlikely the D-backs will generate much traffic on the basepaths.
