CLEVELAND — The Cleveland Guardians tore through Detroit and Philadelphia en route to a 6-1 road trip that has them sitting comfortably atop the AL Central. In those seven games, they allowed 12 runs. Here are some more numbers to consider one-third of the way through the season.6th: The Guardians’ rank in starting rotation ERAThe group has registered a 3.46 ERA, following another gem from Parker Messick on Sunday. Ho hum, another year in which the Guardians’ strength is one of the league’s most proficient rotations. Over the last two weeks, their starters’ ERA is 2.16. Here’s what that looks like in the form of earned runs allowed each game: 0, 0, 0, 0, 0, 1, 2, 2, 2, 2, 3, 3, 4. The simplest way for a team to get on a roll? Consistently great starting pitching. Maybe more teams should just try to do that.139: The highest wRC+ of any hitter on the GuardiansIn simple terms, the Guardians’ hitter who has been most adept at creating runs this season has done so at a rate 39 percent better than league average. Can you guess the identity of this mystery man? It’s not future Hall of Famer José Ramírez (111). It’s not rookie sensation Chase DeLauter (126). It’s not two-time All-Star Steven Kwan (78).It’s the other rookie sensation, Travis Bazzana, the club’s new leadoff hitter. He went 3-for-4 with a home run on Sunday to blitz past a couple of his teammates. He’s been everything the Guardians could have dreamed of and more, with a .294/.400/.424 slash line through his first 100 plate appearances as a big-leaguer.DeLauter’s 126 wRC+ is tied for second on the team, with Brayan Rocchio, who has played at an All-Star level.1st: The Guardians’ rank in walk rate and stolen bases in MayThis is like the patented “Guards Ball” on stero— nope, not that. Let’s say it’s like a turbo-charged version of “Guards Ball.” They’re walking a ton and running a ton, and when they deliver timely hits or flex some muscle at the plate, the offense gets dangerous. Overall, it’s been about a league-average attack, but that’s light years ahead of where it was last year. Last season, the Guardians posted an 87 wRC+. This year (as of Sunday morning), they’re at 99. In May, they’re at 102, which ranks 10th in the league, and they also rank second in strikeout rate and ninth in home runs.55: Days between three-hit games for Steven KwanSam Merrill banked in a 3-pointer for the Cleveland Cavaliers during their Game 3 loss to the New York Knicks, which led broadcast analysts Tim Legler and Richard Jefferson to debate whether an errant-yet-fruitful shot could boost a cold shooter’s confidence. Kwan entered the Guardians’ series finale Sunday with the league’s 10th-worst OPS (.572), but he beat out an infield tapper in his first at-bat, and that spurred him to his first three-hit game since March 30. Whatever it takes to get a hitter (or a shooter) on track, right? Kwan had three multi-hit games in the first five games. He has seven in 46 games since.2.48: The Guardians’ bullpen ERA since April 18That’s an arbitrary endpoint, conveniently chosen as the day after an eighth-inning meltdown against the Baltimore Orioles. Five weeks is a healthy sample, though, and in that span, the Guardians’ bullpen has been the best in baseball. That’s because Cade Smith once again looks like the soul-destroying strikeout artist who led all relievers in WAR each of the last two years (and ranks third this year). In his last 13 outings, he has allowed one earned run, with one walk and 21 strikeouts. He has converted 15 consecutive save opportunities.It’s also because Erik Sabrowski, who owns a career 1.43 ERA, continues to thrive in a setup role, because Colin Holderman has emerged as a reliable, high-leverage option and because Hunter Gaddis has looked like his old self lately.2: Number of Cleveland pitchers with 200 innings and 250 strikeouts in a season in the last half-centuryThere’s a long way to go, of course, but Gavin Williams is on pace to be the third. He’d join Shane Bieber (2019) and Corey Kluber, who accomplished the feat in both of his Cy Young Award seasons (2014, 2017). Williams authored one of the best starts of his career on Friday, when he went toe-to-toe with Phillies ace Cristopher Sánchez and piled up 11 strikeouts over eight scoreless innings. Williams tossed five scoreless frames against the Phillies last May, too. Since, in 35 starts, he has recorded a 2.81 ERA, with 257 strikeouts across 205 innings.5: Number of starting pitchers the Guardians have usedWhen a reporter mentioned this to Stephen Vogt in Detroit last week, the manager tapped his knuckles on the dugout bench for good luck. Even though Cleveland is known for its pitching factory and the rotation has been the club’s backbone, it’s actually the area in which they have the least major league-ready depth. Health and reliability have been paramount, and Vogt admitted they’ve used caution at certain points so they can keep this group in one piece.Last year, the Guardians used 10 starting pitchers. The year before, they used 12, plus two relievers as openers. Eventually, they’ll need a sixth starter, and likely more than that. For now, though, they’re buying time for their depth to materialize, whether it’s building up Austin Peterson or allowing Khal Stephen to fine-tune his secondary stuff..806: The Columbus Clippers’ team OPSThat’s actually come down a bit in recent days. (The International League average is .761, for what it’s worth.) It’s a good reminder that while DeLauter and Bazzana have graduated to the big leagues, there’s plenty of backup two hours south.Kahlil Watson (.879 OPS) should factor into the outfield mix at some point this year. Vogt is a fan of his former teammate, Stuart Fairchild (.928 OPS), who could be a right-handed option in the outfield. Angel Genao (.865) and Ralphy Velazquez (.804) were recently promoted to Columbus and might be the organization’s top two prospects. Catchers Cooper Ingle (1.157) and Kody Huff (.922) have thrived. Milán Tolentino (.770) could be a future utility infielder. Familiar faces CJ Kayfus, George Valera, Juan Brito and Nolan Jones are all in Columbus as well. There’s a lot of talent — or, a lot of trade ammunition.4: Number of AL teams with a winning recordThe Tampa Bay Rays are cruising. The New York Yankees, like the Guardians, are nine games over .500. The Athletics sit one game over .500. And that’s it. In other words, the AL is wide open, and the Guardians appear as competent as anyone. An entertaining summer (and fall) could await Cleveland. The front office ought to remain aggressive to capitalize on the lack of potent competition.
