TORONTO -- The struggling Padres shook up their roster on Tuesday afternoon, making a flurry of moves prior to their series opener against the Blue Jays.

Perhaps most notably, catcher Luis Campusano has returned after missing three months due to a left thumb injury that required surgery. But the Padres didn¡¯t stop there. They promoted outfielder Taylor Kohlwey, who will be making his big league debut, and first baseman Alfonso Rivas from Triple-A El Paso.

To clear space, catcher Austin Nola and utility man Brandon Dixon were optioned to El Paso, while Rougned Odor was designated for assignment.

Here are some quick takeaways on the Padres¡¯ busy day:

1. The Padres needed a shakeup
Having lost three of four out of the break, the Padres¡¯ season was teetering. They¡¯re six games below .500 and eight games out of a playoff spot with the Trade Deadline fast approaching. If there were ever a time to shake things up and see what works ¡­ this was it.

As such, the Odor move may have come as a surprise, but certainly not a shock. The veteran infielder was immensely clutch for the Padres in May (four homers and 15 RBIs). But he was hitting just .189/.268/.243 over the past month.

¡°Rougie was really well liked here, got off to a good start,¡± manager Bob Melvin said. ¡°Here recently, maybe [he was] not as good. But I think it¡¯s maybe more: When the team¡¯s not playing well, you try to make some adjustments.¡±

Enter Kohlwey and Rivas, a pair of left-handed hitters who had little else to prove in the hitter-friendly Pacific Coast League. The Padres figured they might as well see what they have to offer.

2. Campusano¡¯s workload
The Padres haven¡¯t loved Gary S¨¢nchez¡¯s heavy workload behind the plate -- and perhaps that workload has led to his recent struggles after a fast start.

Campusano has a chance to earn a larger share of the playing time than what Nola was afforded. The Padres envisioned big things for Campusano in his age-24 season, touting the strides he¡¯d made defensively and his impact at the plate. Then he went down with injury two weeks into the season.

¡°I thought it was coming together,¡± Campusano said. ¡°It¡¯s just comfort, I was comfortable. I still feel that way, nothing¡¯s really changed. It¡¯s just a little setback, but I¡¯m here now, so I¡¯m ready to go.¡±

Melvin noted that Campusano is expected to start on Wednesday in Toronto, but he wouldn¡¯t commit to a firm plan behind the plate, saying only, ¡°We¡¯ll make the best lineup we can for that particular day.¡±

As for Nola, his 2023 season has been disappointing, but the Padres were pleased he had an option year remaining, so he remains in their system.

¡°Go down there and get some at-bats, because he¡¯s a better player than he¡¯s shown here,¡± Melvin said. ¡°Recently obviously, he hasn¡¯t played a ton. The workload has been pretty extreme for Gary, so Campy is going to get a share of games.¡±

3. Organizational stability
Recently, the Padres have promoted Matthew Batten, Alek Jacob, Ryan Weathers (since optioned) and now Kohlwey. On a roster that didn¡¯t previously feature many homegrown players, it¡¯s a stark shift.

And perhaps a purposeful one.

¡°There¡¯s that pride factor with guys that come up in your system and have been there a while,¡± Melvin said. ¡°There needs to be an avenue to the big leagues. ¡­ I don¡¯t know [if] that was the reason for it. But I think that more guys from our system getting here is probably a good thing for the organization.¡±

As for Kohlwey, he was at the movies Monday night, 30 minutes into the latest "Mission: Impossible" film. That¡¯s when he got a text from Triple-A manager Phillip Wellman telling him he needed to leave the theater. Shortly thereafter, Wellman delivered the news, and Kohlwey was on his way to Toronto.

¡°I¡¯m just going to try to soak it all in, do my best and just get better every day,¡± Kohlwey said. ¡°Try to help in whatever way I can.¡±

The Padres expect to use Kohlwey in a number of capacities as a versatile outfielder, a solid runner and a lefty-hitting pinch-hit weapon.

And when he¡¯s done all that, maybe he can catch the rest of "Mission: Impossible."
