Cleveland Guardians Sports Betting Picks MLB DraftKings Sportsbook Insights

Hope springs eternal in the AL Central. Despite their sub-.500 record, the Guardians (61-65) still have a shot at bringing home their third consecutive division title. Even if that doesn’t work out, the American League’s final wild card spot is currently occupied by 62-64 Texas. In short, there are multiple paths to postseason baseball for Cleveland. Still, that doesn’t mean this club can afford to keep losing. That gives added importance to Wednesday’s matchup with the rebuilding Giants (51-74). Will the Guards clinch a series win this evening at home?

The Guardians are favorites (-218) over the Giants; the over/under is set at 7.5 runs. Below, I’ve laid out my preview, prediction, and best bet for Wednesday’s showdown between San Francisco and Cleveland on DraftKings Sportsbook.

Giants vs. Guardians pick, best bet today

  • Guardians -1.5 First 5 Innings (+124): For those looking to get decent value tonight, back the Guardians to score early. Wilkinson is unproven, and could get pulled after three or four innings. In comparison, Messick should keep this dismal Giants offense at bay.

Giants vs. Guardians prediction, preview

It’ll be Matt ‘Tugboat’ Wilkinson making his major league debut tonight at Progressive Field. His numbers at Triple-A Sacramento aren’t great (5.15 ERA), but pitching isn’t easy in the hitter-friendly Pacific Coast League. Funnily enough, the Vancouver naive was traded to San Francisco by Cleveland as part of May’s Patrick Bailey trade. Now, he’ll get to face his former organization on the road. Wilkinson has done a stellar job at limiting quality contact. He owns a stellar 5.9 H/9 ratio over 20 appearances in the minors this season. The 23-year-old has been kept on a short leash, tossing more than 5.0 innings on just four occasions. A similar restriction will likely be put in place tonight by Giants manager Tony Vitello.

There isn’t a ton to brag about when it comes to this Guardians offense. However, the club is tied for the 11th-most runs in baseball (69) over its last 15 matchups. They’re also averaging more runs at home (4.14) than on the road (3.83). New acquisitions Nathaniel Lowe (128 wRC+) and Jo Adell (125 wRC+) have been a positive, while rookie Angel Genao (150 wRC+) already looks like a franchise cornerstone. Even more important, some of the team’s established players are getting back on track. Over Cleveland’s last ten games, All-Stars Jose Ramirez and Steven Kwan have both delivered an OPS greater than .800. Ditto for outfielder Chase DeLauter, who was named AL Rookie of the Month for July. Of note: both Adell (knee) and DeLauter (hamstring) are listed as day-to-day.

What gives the Guardians an even bigger boost is tonight’s starter, Parker Messick. The rookie has been a revelation, emerging as the ace of a stellar pitching staff. Through 142.1 innings (24 starts), he’s recorded a 2.59 ERA, 1.03 WHIP and 142 strikeouts (9.0 K/9). The southpaw is a true jack of all trades, placing within the 69th percentile or better in strikeout rate, walk rate, barrel rate, and hard-hit rate. Just as important, he’s done a good job at limiting the long ball (0.9 HR/9). Messick has allowed two earned runs or less in each of his previous seven outings.

Despite some signs of improvement earlier this season, the Giants are among the league’s worst offenses. They’re 25th in runs scored (510) and 27th in on-base percentage (.306). Keep in mind, this club recently traded away All-Star second baseman Luis Arraez and outfielder Helliot Ramos. To make matters worse, Willy Adames (back) and Matt Chapman (abdomen) are on the injured list. Unsurprisingly, San Francisco has scored the third-fewest runs in baseball over its last ten games (31). In addition, the club has delivered a National League-worst .666 OPS against left-handed pitching.

Best Bet: Guardians -1.5 First 5 Innings (+124)

Messick is blossoming into an ace, making this an uphill climb for San Francisco’s undermanned lineup. In comparison, the Guardians are beginning to look more respectable at the plate. At home, I like their chances at getting to the unproven Wilkinson. Don’t be shocked if the home favorites jump out to a comfortable lead on Wednesday.
