Seattle Mariners

John McGrath’s major league power rankings

1. St. Louis Cardinals (1): After 18-day layoff, Lance Lynn looked like ace in return vs. Marlins.

2. Kansas City Royals (4): Royals taking appropriate, business-as-usual mindset into rematch of wild early-season series against A’s.

3. Houston Astros (5): Starting pitcher Dallas Keuchel might be only shoo-in All Star for first-place ’Stros.

4. Pittsburgh Pirates (7): Jose Tabata always will be remembered as the killjoy who used an elbow pad to break up Max Scherzer’s perfecto.

5. Los Angeles Dodgers (2): Versatile journeyman infielder Justin Turner will draw some votes in MVP race.

6. Tampa Bay Rays (10): Outfielder Joey Butler, 29, could be oldest AL Rookie of the Year since former M’s closer Kazuhiro Sasaki won the 2000 award at age 32.

7. Washington Nationals (12): Scherzer making his fellow Mizzou alums proud.

8. Minnesota Twins (8): Brandon Buxton’s thumb sprain on unsuccessful stolen-base attempt summed up frustration of heralded rookie’s 11-game debut.

9. Chicago Cubs (9): Shortstop Starlin Castro is Cubs most prominent trade chip for acquisition of a starting pitcher.

10. San Francisco Giants (6): Jake Peavy (back) and Matt Cain (flexor tendon) aiming at simultaneous return to rotation next week.

11. New York Yankees (3): Jacoby Ellsbury, sidelined since May 19 with a sprained knee, probably won’t be available on everyday basis until mid-July.

12. Baltimore Orioles (20): Right-handed pitching prospect Pat Connaughton, a 6-foot-5 Notre Dame shooting guard, planning on pursuing hoops career after second-round selection in NBA draft.

13. Toronto Blue Jays (15): Relentless hitting attack — they lead the league in six categories, including batting average, on-base and slugging percentages — has Jays primed for first playoff appearance since ’93 World Series.

14. Detroit Tigers (16): Venezuelan reliever Bruce Rondon, whose fastball was clocked at 101 mph last week, is named after the late martial-arts legend Bruce Lee.

15. Los Angeles Angels (13): A year after leading MLB in runs scored, offense is sputtering.

16. Texas Rangers (14): Rookie slugger Joey Gallo must adjust to steady diet of low-and-away pitches.

17. New York Mets (11): Injury-depleted, depth-deprived Mets desperate for a jack-of-all-tradesman such as A’s Ben Zobrist.

18. Arizona Diamondbacks (23): The future isn’t now, but it’s getting closer: D-Backs’ lineup includes seven regulars no older than 27.

19. Atlanta Braves (19): Over seven starts since May 17, right-handed ace Shelby Miller has put together a 2.70 ERA and an 0-2 record.

20. Cincinnati Reds (22): Pete Rose bet on baseball games as a player? Get out!

21. San Diego Padres (17): Former M’s pitcher Brandon Maurer gave up two earned runs in a relief appearance Thursday — or as many as he surrendered since April 29.

22. Cleveland Indians (18): Jason Kipnis, who began last week leading the league’s second basemen in batting average, hits, triples, walks, OPS and Wins Above Replacement, ranks fourth in A.L. All-Star balloting.

23. Oakland A’s (28): Thursday victory over Rangers snapped string of 48 days spent in last place.

24. Seattle Mariners (26): Season still can be salvaged with two-week long hot streak, but that’s a lot to ask of a team that has yet to win more than four in a row.

25. Colorado Rockies (24): Cut on left middle finger deprived Jorge De La Rosa from winning decision in eponymous pitching matchup against Arizona’s Rubby De La Rosa.

26. Chicago White Sox (21): Until he’s told he’s no longer wanted, manager Robin Ventura will do things his way.

27: Boston Red Sox (25): In wake of Rusney Castillo’s demotion to minors, Sox have to be wondering if the seven-year, $72 million contract they gave to the Cuban outfielder was a mistake.

28. Miami Marlins (27): Former Cy Young Award winner Jose Fernandez nearing finish line of 13-month rehab following Tommy John surgery.

29. Milwaukee Brewers (29): Brewers happy Virginia closer Nathan Kirby, their second pick in the draft, stayed out of the celebratory dogpile after his five-strikeout save clinched College World Series.

30. Philadelphia Phillies (30): With front-office overhaul afoot, ex-manager Ryne Sandberg didn’t need to squint to see writing on the wall.
