Angels’ David Fletcher is surging at the plate, so why is he batting No. 9?

A week that began with a disappointing three-game sweep at the hands of the Oakland Athletics ended with three of four wins against the Detroit Tigers, a stretch of extremes in which the one constant was Shohei Ohtani, who hit six homers and drove in nine runs in his last six games.

Here are three observations of the Angels, who are 36-36 and 7 ½ games behind the Houston Astros and Oakland Athletics in the American League West entering Tuesday night’s game against the San Francisco Giants, who have a major league-best 46-26 record:

Leading man

Manager Joe Maddon acknowledges that his lineup would probably function best with a healthy and productive David Fletcher at the top of the order. The contact-hitting second baseman batted first in all but one of his 49 games in 2020, when he hit .319 with a .376 on-base percentage and scored 31 runs.

“I think if you want to speak in theoretical terms, before the season began,” Maddon said, “you would think that.”

Fletcher spent the first month and a half of 2021 in the leadoff spot before being demoted to the ninth spot with a .250 average and .271 on-base percentage May 15.

Maddon moved middle-of-the-order slugger Justin Upton, who had never hit leadoff in 14 previous big-league seasons, to the top spot on May 23, and in 24 games since, all but one in the leadoff spot, Upton has hit .333 with a .427 OBP, six homers, eight doubles, 15 RBIs and 25 runs.

Fletcher has since regained his stroke, hitting .327 (34 for 104) with a .369 OBP, seven doubles, 11 RBIs and 18 runs in 31 games in the ninth spot, but even when Maddon gave Upton a day off on Sunday, he kept Fletcher at the bottom of the order.

“Of course, I did think about it,” Maddon said of moving Fletcher to the leadoff spot for one game, “but I don’t want to mess with his mojo now, it’s been fabulous. There’s been a lot of action at the bottom, and he’s taken care of that really well.”

So well, in fact, that Maddon said he has “no intentions” of moving Upton out of the leadoff spot when star center fielder and three-time American League most valuable player Mike Trout returns from a left-calf strain in July.

“I’m in no hurry to get J-Up out of the leadoff spot,” Maddon said. “He’s gotten plenty of opportunities to drive in runs there. The biggest thing with J-Up at the top is he’s really setting a strong tone for the whole group with his ability to accept his walks and drive the ball and his baserunning. It kind of works.”

Rendon’s bat lagging

The Angels lost five of their first six games after Trout was hurt May 17, hitting .206 with a .694 on-base-plus-slugging percentage and averaging 3.8 runs and 6.2 hits per game. They went 17-9 in their next 26 games, hitting .278 with an .819 OPS and averaging 5.9 runs and 9.5 hits per game.

But if the Angels are going to continue to weather the loss of Trout and make some kind of playoff push in the second half, they’re going to need much more production from third baseman Anthony Rendon, who has been among baseball’s most disappointing players in 2021.

Rendon, in the second year of a seven-year, $245-million deal, went hitless in four at-bats in Sunday’s 5-3 loss to the Tigers, striking out twice and hitting into a double play, and is batting .230 with a .653 OPS, four homers, nine doubles and 30 RBIs in 47 games.

He has been on the disabled list twice this season, because of a left-groin strain in early April and a left-knee bruise in early May, and he missed four games last week because of a left-triceps injury he suffered while diving for a double down the line in Oakland on May 14.

“He’s shown some flashes of coming out of it on occasion,” Maddon said. “The biggest thing for me, from a technical perspective, is he’s laying back a little too much, kind of being not on time. When he is on time, there’s a flatter, more timed-out approach to the ball and the trajectory is better. Every time he’s off for a couple of days, this seems to happen.”

Maddon insisted after Sunday’s game that Rendon is “OK” physically. Though Rendon has suffered a series of injuries, “he doesn’t complain of anything,” Maddon said. The manager remains confident that Rendon will snap out of his season-long funk.

“I have absolute faith in this guy, I know he’s gonna get hot,” Maddon said. “He knows exactly what he’s working on. I’ve spoken to him and watched his work, and I’m very encouraged that he’s going to get better.”

Star attraction

The Angels have been unable to mount much of a threat in the division, but they were smart to maximize Ohtani’s box-office potential both this week and next.

Ohtani’s next start on the mound was pushed up to Wednesday’s 1 p.m. game in Angel Stadium, setting up a marquee pitching matchup between the two-way star and Giants ace Kevin Gausman, who is 8-1 with a major league-leading 1.51 ERA.

Griffin Canning was pushed back to Friday’s series opener at Tampa Bay to accommodate Ohtani, who is 3-1 with a 2.70 ERA in 10 starts this season, striking out 73 and walking 29 in 53 1/3 innings.

Not only will the move increase attendance for the final game of the Angels’ homestand, it will put Ohtani in line to make his first-ever pitching start in Yankee Stadium next week.
